Answer:
public class Main
{
public static void main(String[] args) {
int carYear = 1995;
if(carYear < 1967)
System.out.println("Probably has few safety features.");
if(carYear > 1971)
System.out.println("Probably has head rests.");
if(carYear > 1992)
System.out.println("Probably has anti-lock brakes.");
if(carYear > 2002)
System.out.println("Probably has tire-pressure monitor.");
}
}
Explanation:
The code is in Java.
Initialize the carYear
Use if statements to handle year before 1967, after 1971, after 1992 and after 2002.
Print the required message for each if statement
Answer:
C. Mean
Explanation:
Mean = (∑
)/N
Median = central values when data is sorted
Mode = most repeated value
Standard deviation = 
In standard deviation, formula you may see that deviation is being calculated from the mean (central location). But here we take square of the value before adding all of them.
But if we just take
, it would be equal to zero.
<u>EXAMPLE</u>
Take 4, 9, 5 as data
mean = (4+9+5)/3 = 18/3 = 6
sum of deviations from mean = (4-6)+(9-6)+(5-6) = (-2)+(3)+(-1) = 0
